Abstract: The invention is a visual alignment aid device that is supported on a towing vehicle to aid in the alignment of the ball on the towing vehicle with the socket in the trailer of the vehicle to be towed, The device includes an elongated tubular shaft having a telescoping shaft sliding and rotationally received therein. The telescoping shaft can be arrested in any position relative to the tubular shaft. The telescoping shaft further has a section with a rigid bend therein. The bend can include an angle of at least 90° and up to 180° depending on the vehicle on which the alignment device is supported. At an end of the telescoping shaft a sleeve is separably mounted which sleeve has an extension which supports a convex mirror in an eccentric fashion.

Abstract: A visual alignment aid device for visually aiding a driver of a towing vehicle to align the ball on the towing vehicle with a socket on the tongue of a trailer. The device includes an elongated tubular member having a telescoping tubular member therein for extending the length of the tubular member. the telescoping member can be arrested in any length and rotational position. The tubular member can be attached to a vehicle by way of magnets or suction cups. An end of the telescoping member has a curved arm attached thereto by way of a clamping hinge. An end of the curved arm has a short arm attached thereto by way of another clamping hinge. The end of the short arm has a convex mirror attached thereto by way of a friction ball swivel.

Abstract: A portable, power operated circular saw having a housing or frame and a base plate pivotally connected at its forward end to the saw housing or frame for swinging movement about an axis parallel the axis of rotation of the blade mounting shaft is provided with new and improved base plate inclination adjustment means comprising an adjustment arm having an elongated arcuate portion provided with an elongated arcuate slot generally concentric the pivotal axis of the base plate and a clamping member extending through the arcuate slot for clamping the adjustment arm selectively at a fixed position relative the saw housing or frame, the clamping member being actuated by relative rotation between a pair of camming members having opposed cooperating interacting inclined ramps or cam surfaces, at least one of the cam members being adapted to be rotated by an operating lever.
